Metabolomics of Vitis davidii Foëx. grapes from southern China: Flavonoids and volatiles reveal the flavor profiles of five spine grape varieties

Abstract

The spine grapes (Vitis davidii Foëx.) are wild grape species that grow in southern China, and can be used for table grapes, juicing and winemaking. To systematically investigate the flavor profiles of spine grapes, flavonoids and volatile compounds were detected in five spine grape varieties (Seputao, Ziqiu, Miputao, Tianputao and Baiputao) using HPLC-QqQ-MS/MS and GC-MS. The content of these compounds highly depended on the variety, such as the total concentrations of anthocyanins (91.43-328.85 mg/kg FW) and free norisprenoids (2.60 to 11.46 μg/kg FW). Seputao contained relatively higher concentrations of anthocyanins, flavonols and free volatile phenols. Baiputao was characterized by higher concentrations of skin flavanols, with more terpenoids and norisoprenoids in the free form. Ziqiu had a higher concentration of bound benzenoids. Miputao had the lowest flavonols. Their characteristic flavor compounds of were subsequently revealed using multivariate statistical analysis. The results helped the producers to further develop and utilize the spine grapes.

Use of Lactiplantibacillus plantarum (ML PrimeTm) to improve malolactic fermentation of catarratto wine subjected to long post-fermentative maceration.

AIM: Lactiplantibacillus plantarum species is wordwide used as starter for malolactic fermentation [1,2]. For the first time, in the present study, the use of L. plantarum (ML PrimeTM, Lallemand wine) to produce white wines with post-fermentative maceration extended until 60 days has been investigated.

Metabolomic study of mixed Saccharomyces cerevisiae yeast during fermentation

Alcoholic fermentation conducted by microorganism is a key step in the production of wine. In this process, interactions between different species of yeast are widely described but their mechanisms are still poorly understood. The interactions studied in wine are mainly between Saccharomyces and non-Saccharomyces species. Therefore, little is known about the mechanisms of interactions

Polysaccharides (PS) are one of the main compounds found in wines, and they come mainly from the grape cell walls or from the yeasts, and they play an important role in the technological and sensory characteristics of wines. Polysaccharides obtained from yeasts have been more studied, especially mannoproteins, since there are commercial products.
